Duolingo shares closed at $172.78 (+2.84%) on November 21, 2025, rebounding after a steep decline in recent weeks triggered by mixed Q3 results and softer-than-expected guidance. The company previously reported strong top-line and profit growth, but investors remain concerned about slowing user growth and the impact of prioritizing long-term expansion over near-term monetization[1][2]. No new major company-specific news or announcements were reported on November 21, 2025. The recent price action appears to be a continued adjustment to the Q3 earnings narrative and broader market sentiment, rather than a response to fresh developments.
